Low levels of hypertension awareness and high proportions of uncontrolled blood pressure in the united kingdom and ireland

Objective: Globally, it is estimated that 10.4 million people die each year due to raised blood pressure (BP). Unfortunately, at least 40% of those with high BP globally are unaware of their condition. In the most recent UK and Ireland community-based data, 66.5% of people were unaware of their high BP(1). The UK and Ireland have taken part in the global May Measurement Month (MMM) campaign, in a bid to increase awareness of BP and to evidence the proportion of those in the community with undiagnosed high BP. The aim of this study was to investigate the large and combined 2017, 2018 and 2019 MMM dataset, to evidence the proportion of people with raised BP, undiagnosed hypertension and levels of hypertension not treated to target in the UK and Ireland. Design and method: As part of the MMM protocol, community-based opportunistic BP screening sites were set up across the UK and Ireland in places of worship, supermarkets, pharmacies, GP surgeries, workplaces, gyms and other public spaces in 2017, 2018 and 2019. A questionnaire recording medical history, lifestyle and demographics was used to collate participant information. BP was measured three times and the average of 2nd and 3rd readings used for analyses. Multiple imputations were performed to impute the mean BP, where data were missing. The term Hypertension was used for those with systolic BP >/ = 140 or diastolic BP >/ = 90 mmHg, or the participant was on BP medication. Controlled BP was considered as < 140 and < 90 mmHg. Results: Data on 22,910 individuals were analysed as part of the combined MMM dataset. Mean age of participants was 52 ± 18 years, with 60% reporting as female gender. See Table 1 below for the proportion of those considered hypertensive, levels of awareness and the proportion of hypertensives treated to target. Conclusion: In the largest community-based BP dataset to date in the UK and Ireland, our data highlight the concerning levels of people with high BP unaware of their condition and poor levels of controlled BP in hypertensive patients. Better community based and primary care screening initiatives are required to improve awareness and early identification of those at high risk of cardiovascular disease.
